SoftRel Short Cut Prediction Model

This model correlates 15 software development practices to defect density. You check the practices you have in place and Frestimate computes the number of predicted defects based on those practices.  While the Full scale model employs an exhaustive list of development practices that have been correlated to defect density, this model has a select set that are generally easy to measure particularly for people who may not be software engineers.

• Software managers use this model for doing tradeoff analyses to determine which practices will result in lower defects in the future as well as identifying practices that may not be reducing defects as well as others.
• Software test managers use this model to gauge the testing effort required to meet a specific quality objective.
• Reliability engineers use this model to predict system reliability.

This is page 1 of the 2 page survey containing 15 questions.

This module contains

• A short multi parameter model for predicting defects, defect density, MTTF, failure rate, MTTCF, critical failure rate, reliability, availability
• Wizards for collecting prediction inputs
• Technical help files for the shortcut model

Key Benefits

• Allows for some trade-offs and identification of some key practices
• Provides richer information then the one parameter lookup charts contained in the Basic Module yet it is quicker then using the detailed models such as the Fullscale or the Rome Labs models.

• Supports software management
• Versatile for software managers, reliability engineers, software process engineers and testing managers
